The influence of the O2-concentration in the nutrient solution on the development of cucumber plants in a special hydroponic-system

Folster, O., 1974: The influence of the O2-concentration in the nutrient solution on the development of cucumber plants in a special hydroponic-system. Acta Horticulturae (37): 2046-2050

A hydroponics system, using PVC tubes to circulate the nutrient solution, is described. Oxygen enrichment was provided by spraying the solution through and over short vertical tubes and also via compressed air. When cucumbers were oxygenated at different levels their shoot growth showed a positive correlation with the O2 level in the solution. The O2 utilization depended on climatic factors.
